I've always been a sucker for good marketing. Case in point, the Starbucks Unicorn Frappucino that was available in a limited supply from April 19 to 23 last week.

This flavor-changing, color-changing concoction topped with whipped cream-sprinkled pink and blue fairy powders was promised to be "available only if you believe" in the majestic powers of the mythical unicorn creature.

I don't know about you, but I do believe and I had to try this shake out for myself.

So just like I did with the McDonald's Shamrock Shake Workout back in March, I decided to create a damage control workout for Starbucks' latest creation.

A 16 oz grande will cost you 410 calories and 59 grams of sugar, which isn't too bad as far as sugary drinks go. But you'll still need a serious workout to enjoy this shake guilt-free, and I have the perfect routine to do just that.

This 30-30 metabolic conditioning circuit is one of my all-time faves. It uses a 30 seconds on, 30 seconds off interval which is ideal for crushing calories during your workout and creating an afterburn effect for up to 48 hours after you're done. Prepare for some serious huffing and puffing, baby.

It also uses one of my favorite fat loss tools, the Assault Airbike, or as some people call it, the Devil's Tricycle.

No other training tool allows you to safely crush yourself like the Assault bike.

It's low-impact and uses both the arms and legs to get more muscle involved.

This translates into a greater calorie burn and a greater oxygen demand.

And what's really unique about this fan bike is that the harder you pedal, push, and pull, the more resistance your body needs to work against.

You can modify with another air bike like an Airdyne or just use a regular cycle or recumbent bike with only leg pedaling options if needed.

You will alternate between an assault bike sprint and 5 moves that collectively work your whole body. Besides the bike, you'll need access to a kettlebell, bouncing med ball, and a bench.

The Unicorn Frappucino Workout

Directions: Do each move for 30 seconds with 30 seconds of rest between moves:

1a. Assault AirBike/cycle sprint

1b. Kettlebell swing

1c. Assault AirBike/cycle sprint

1d. Unicorn hands-elevated plyo pushup

1e. Assault AirBike/cycle sprint

1f. Rainbow med ball slam

1g. Assault AirBike/cycle sprint

1h. Alternating split jump

1i. Assault AirBike/cycle sprint

1j. Rainbow leg raise

That's 1 round. Do up to 4 total rounds, resting 2 to 3 minutes between rounds.

Sadly, by the time I did the workout and went to our local Starbucks here in Emmaus, Pennsylvania, they were completely sold out. Much like the unicorn, it vanished as quickly as it appeared, leaving us all unable to either confirm or deny its existence.

However, I can confirm that this is one helluva total body workout you can do anytime to burn fat, build muscle, and occasionally make some room for some eats and treats. The hooves, body glitter, and unicorn mask are optional.
